When the new junction was first opened, a camera was placed overlooking the roundabout on the roof of the adjacent Kodak HQ building. It was noted many drivers would get 'lost' and make repeated reversals of direction between joining the roundabout and eventually leaving it.

It's actually wrong. The article states a few times that it's a bi-directional roundabout. It's not. There is no central roundabout, it just looks like one. It's actually just 6 small roundabouts with roads between.
